The SSPL does not place restrictions on purpose of use unless you also believe the AGPL does. You can diff the two licenses and see that the part which some people consider to be a purpose of use restriction is identical.
The OSI declared it nonfree, because the OSI is a consortium of large companies - cloud service providers and the like.
The FSF decided not to issue any opinion.
Debian decided not to issue any opinion, but because it was only affecting a few packages and they have good GPL counterparts, switched to the GPL counterparts anyway.
There is no evidence the SSPL is nonfree. That is big tech disinformation. Please don't spread it. What the SSPL actually is is an extreme point in the WTFPL-to-AGPL spectrum - it's more AGPL than AGPL itself. It's still on that spectrum, not a completely different spectrum like a proprietary license.
It is actually terrifying how successful the cloud provider cartel has been at spreading FUD about SSPL. Denied OSI certification and packages getting dropped from repos?
Debian has an unusually strict policy that will absolutely err on the side of not including packages (famously not packaging things you need, like video drivers) and valkey is simply better than redis anyway (more features, better performance) and is drop-in compatible, so it was an easy choice for them.
